Yup. Most of the anti-cheats have been ported to Proton at this point. Usually when games don't enable it, its because the games haven't been well-engineered and are too easily exploitable.

Destiny 2 is another example, turning on BattlEye on Proton is literally flipping a switch in the SDK. And they had a Destiny build for Linux because it was running on Stadia. But Destiny has a horrible codebase, and even with BattlEye on Windows there is a decent chunk of hard cheating.

And its not that just the non-competitive games choose to allow Proton. Halo and Apex Legends are good examples that play on Proton.
